Detailed ways

The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

Fig. 1 shows the flow chart of the incoming call notification method according to the first embodiment of the present invention, the method includes the following steps:

Step 101, the UE receives the chromatic image data from the CRS AS, and plays the chromatic image according to the chromatic image data;

Step 102, the UE judges whether the UE completes the access handover;

Step 103, if the access handover has been completed, the UE stops playing the chromatic image, and prompts the user for an incoming call with a local ring.

In this embodiment, when the terminal receives and plays the chromatic image, when the access switch occurs, the terminal stops the chromatic image service after judging that the local access switch is completed, and instead provides the user with the incoming call information by local ringing. After the switching is completed, the terminal actively stops the chromatic image service, and starts to provide the user with incoming call information in the form of a local ringing prompt, so that the user can still know the correct incoming call information even when the terminal access switch occurs, which improves the reliability of the incoming call prompt , which improves the user experience, so it overcomes the incoming call notification method in the related art. If the terminal continues to receive and play the chromatic image resource data in the packet domain from the network, the access switching will cause the interruption of the reception of the chromatic image data of the terminal. There is a phenomenon that the terminal has no sound or image when accessing and switching, which leads to the problem that the called user cannot identify the calling user because he cannot get the notification of the incoming call, and even misses the incoming call.

Fig. 2 shows the flow chart of the access handover method according to the second embodiment of the present invention. The UE in this embodiment is the called terminal. The UE first accesses in the packet domain, and the access occurs during the ringing process. To switch, specifically include the following steps:

Steps 201-204, a standard SIP (Session Initiation Protocol, Session Initiation Protocol) session, the UE is ringing at this time, prompting the user to have a voice call session, wherein I/S-CSCF (Interrogating/Serving Call Session Control Function) is the inquiry /service call session control function;

Step 205 , at this time, due to the change of location, the UE receives a test report from the network indicating that the CS network signal is better, and needs to switch the PS session access to the CS network. The access layer network element, such as MME (Mobility Management Entity, mobility management entity), notifies MSC (Mobile Switching Center, mobile switching center) that access switching is required, and MSC initiates an access switching request to the IMS network, and MSC Server Access handover indicates its ability to support intermediate call services, and the access handover request is, for example, an INVITE message of SIP;

Step 206, standard SIP routing process, S-CSCF forwards the access switching request to SCC AS (Service Centralization and Continuity Application Server, service centralization and continuity application server);

Step 207: After receiving the access handover request, the SCC AS finds out the ongoing voice call of the UE according to the content of the request and updates it, mainly updating the UE's media support type and address; in this step, the SCC AS may not update according to the media negotiation Remote media description; at this time, it is assumed that the initial media negotiation is completed before the access handover is triggered, so that the SCC AS can update the remote;

Step 208, the SCC AS provides the session state information of the incoming call: the ringing state, the session state information in this step can be used as a part of the content of the message that the SCC AS responds to the INVITE;

Step 209, the S-CSCF forwards the session state information to the MSC Server;

Step 210, the MSC switches to the corresponding CS call state: the call is received;

Step 210b, performed simultaneously with step 210, the UE receives the HO (Hand Over, access handover) command, and determines the local state of the SIP session, and then creates a corresponding CS call state: when the call is received, the UE continues to prompt the user for an incoming call;

Step 211, the user presses the key to answer;

Step 211b, the UE changes the state to the active state;

Step 212, the UE sends a CS connect (connection) message to the MSC Server using a standard CS procedure;

Step 212b, MSC Server also changes state to active state;

Step 213, the MSC Server notifies the SCC AS: the user has answered the call;

Step 214 is a standard procedure: the S-CSCF forwards the notification message to the SCC AS;

Step 215, the SCC AS creates a corresponding SIP message request to send to the remote end, and updates the remote media description.

This embodiment realizes the access switching during the ringing process of the UE, so that the UE is always connected to a network more suitable for the current network situation, and the communication quality is guaranteed.

Preferably, in the above method, step 102 specifically includes: the UE judges whether the call processing state of the UE changes.

The UE in this embodiment judges whether the access handover is completed by judging whether the call processing state of the UE has changed. As shown in the steps in FIG. 2, when the UE completes the access handover, its call processing state must change, so It is feasible to judge the completion of the access handover through the call processing state. For example, the UE originally provided PS sessions for users. However, due to changes in the location of the UE, the current network test results show that the CS network signal is better than the PS network signal. It is necessary to switch the session from the PS network to the CS network. When the UE detects itself If the call state of the user is switched from the original PS call state to the CS call state, it is considered that the access handover has been completed. In this way, the UE can more simply and reliably judge whether the access handover is completed.

Preferably, in the above method, step 103 specifically includes: if the access handover has not been completed, the UE continues to play the chromatic image.

In this embodiment, it is judged that handover access is not performed, and at this time, the UE continues to receive and play the chromatic image. Fig. 3 shows a flowchart of a method for playing a chromatic image according to a third embodiment of the present invention. In this embodiment, the UE does not need to perform access switching. At this time, the UE always prompts by playing a chromatic image before the user presses a button to answer the call. When a user calls, the specific process is as follows:

Step 301, the calling terminal UE1 sends a session request message, and the request message reaches the core network CN (Core Network), wherein the session request message is, for example, an INVITE message of SIP, and the core network is, for example, x-CSCF, HSS (HomeSubscriber Server, home user server) and other IMS server equipment, usually set chromatic image related parameters in the user data on the HSS, and the S-CSCF judges the route according to the user data in the HSS, and first transmits the INVITE message to the chromatic image server CRSAS ;

Step 302, the CN forwards the session request message to the CRS AS, and the CRS AS executes local business logic, and transmits the session request message to the called terminal UE2 through the CN, and the media description data of the chromatic image resource can also be carried in the session Pass it to UE2 in the request message;

Step 303, UE2 returns the called idle message to the CN when it is idle, and the message reaches the server, wherein the called idle message is, for example, a 180 ringing message of the SIP protocol, and the message carries the media description data of UE2;

In step 304, the CRS AS establishes a media data transmission connection with UE2, and the chromatic image data is sent to UE2. In this step, the device sending chromatic image data may be a special media device in the chromatic image server system, such as a device that specifically stores chromatic image resources. The media server, under the instructions of the chromatic image control system, establishes a connection with UE2 and transmits chromatic image media data, and UE2 displays the chromatic image media;

Step 305, the CRS AS sends a called idle message to UE1 via the CN, the called idle message is, for example, a 180 message of the SIP protocol;

Step 306, after the called user presses the button to answer, UE2 sends a called response message, the called response message is, for example, a 200 OK message of the SIP protocol;

Step 307: After receiving the called response message from UE2, the CRS AS stops UE2 from transmitting chromatic image media data, and sends a called response message to UE1 via the CN, and the called response message is a 200 OK message of the SIP protocol;

Step 308, UE1 receives the called response message, sends a session establishment confirmation message, and arrives at the CRS AS via the CN. The session establishment confirmation message is, for example, an ACK message of the SIP protocol;

Step 309, the CRS AS receives the session establishment confirmation message from UE1 and forwards it to UE2 via the CN, the session establishment confirmation message is an ACK message of the SIP protocol;

Step 310, the chromatic image service ends, and the calling party and the called party talk.

In this embodiment, through message interaction and data transmission between the terminal and the network side, it is realized to prompt the user for an incoming call by playing a color image.

In the IMS system, there are other methods for playing chromatic images. For example, the server transmits the link URL (Uniform Resource Locator, Uniform Resource Locator) of chromatic image resources to the terminal in the session message, and the terminal downloads the chromatic image resources and displays them for playback. .

Preferably, in the above method, the UE stopping playing the chromatic image specifically includes: the UE disconnects the service connection with the CRS AS; the UE stops playing the chromatic image.

In this embodiment, it is judged that the access handover has been completed. At this time, the UE stops receiving the color image data by disconnecting the service connection with the CRS AS, and then stops playing the color image. In this way, after the UE determines to perform the access handover , there is no need to process the chromatic image data, which saves resources of the UE and realizes timely stop of the chromatic image.

Preferably, in the above method, the UE using a local ring to prompt the user for an incoming call specifically includes: the UE playing a local ring tone file for prompting the user for an incoming call. In this embodiment, the UE prompts the user by playing a local ring tone file. Since the local ring tone file is inherent in the UE, the local ring tone file will be played when network access switching occurs and the chromatic image service dependent on the network is affected. sound files, improving the reliability of incoming call notifications.

Preferably, in the above method, the UE notifying the user of an incoming call by local ringing specifically includes: the UE notifying the user of an incoming call by vibrating. In this embodiment, the UE uses the vibration method to remind the user. Since the vibration is inherent in the UE, when the network access switching occurs and the chromatic image service dependent on the network is affected, the vibration method improves the reliability of the incoming call notification. .

Preferably, in the above method, the UE prompting the user for an incoming call with a local ringtone specifically includes: playing a local ringtone file while the UE vibrates to prompt the user for an incoming call. In this embodiment, the UE uses vibration and ring tone to remind the user. Since both vibration and ring tone are inherent in the UE, when a network access handover occurs and the chromatic image service that depends on the network is affected, the vibration plus ring tone is used. The way of the ring tone improves the reliability of the incoming call prompt.

The terminal can select one of ringtone, vibration, or ringtone plus vibration according to the policy predetermined by the user for incoming call notification.

Fig. 4 shows a flow chart of an incoming call notification method according to the fourth embodiment of the present invention. In this embodiment, UE1 is the calling party, and UE2 is the called party. The UE2 first accesses in the packet domain, and plays the chromatic image Access handover occurs in , which specifically includes the following steps:

Steps 401 to 407 are standard SIP sessions with chromatic image services. The UE is receiving chromatic image data and playing it, prompting the user to have a voice call session. At this time, it is assumed that the initial media negotiation has been completed and the terminal has started to play chromatic images; in order to achieve Color image business effect, the terminal must play color images from the network, such as voice, text, picture, video, etc., at this time, the local ringing tone of the terminal is suppressed;

Step 408, when an access handover occurs at this time, MSC and UE2 change states respectively, and SCCAS is responsible for completing the relevant functions of the corresponding anchored session;

Step 409, UE2 disconnects the media data connection with the CRS AS at this time, and no longer receives media from the network, which means that UE2 no longer plays/displays the chromatic image. In order to achieve the effect of reminding the user that there is an incoming call, UE2 opens the local ringtone file , play the local ringtone and remind the user, and the UE can also remind the user in the form of vibration or vibration plus ringtone according to the preset;

Step 410, the SCC AS updates the remote end;

Step 411, CRS AS stops sending chromatic image media data;

Step 412, the called user answers and responds, UE2 sends a CS connect message, which is converted into a SIP message by the MSC and arrives at the SCC AS;

Steps 413-416 are the standard SIP session process, because the switch occurs, the chromatic image ends before the called party answers;

Step 417, the SCC AS forwards the session establishment confirmation message, which is converted into a CSconnect ACK message by the MSC and reaches UE2;

Step 418, the calling party communicates with the called party.

This embodiment realizes that when the UE receives chromatic image media and access switching occurs, the terminal turns to play a local ringtone to prompt the user after the access switching is successful, which not only realizes the correct playback of chromatic images, but also ensures access switching And can prompt the user to call.

A judging module 502, used for the UE to judge whether the UE completes the access handover;

The local ringing module 503 is used for, if the access handover is completed, the UE stops playing the chromatic image, and uses the local ringing to prompt the user to call.

In this embodiment, the chromatic image playback module 501 is first used to receive and play the chromatic image, and then the UE uses the judging module 502 to judge whether the UE has completed the access handover. If the access handover has been completed, the local ringing module 503 is used to stop the chromatic image service , and then use local ringing to provide incoming call information to the user. In this embodiment, when the UE receives and plays a chromatic image, access switching occurs, the UE stops the chromatic image service after judging that the local end access switching is completed, and turns to the Local ringing is used to provide the user with incoming call information. Since the terminal actively stops the chromatic image service after the access switching is completed, it starts to provide the user with local ringing prompts to provide incoming call information, so that even when the terminal access switching occurs Still know the correct incoming call information, improve the reliability of the incoming call notification, improve the user experience, so overcome the incoming call notification method in the related art if the terminal continues to receive and play the chromatic image resource data of the packet domain from the network. Access switching will cause interruption of terminal chromatic image data reception, and there will be no sound or image when the terminal is accessing switching, which will cause the called user to be unable to identify the calling user because they cannot get notification of the incoming call, or even miss the call. Problem with incoming calls.

Preferably, in the above apparatus, the judging module 502 is specifically: a status judging unit, used for the UE to judge whether the call status of the UE changes.

The UE in this embodiment judges whether the access handover is completed by judging whether the call state of the UE has changed. As shown in the steps in Figure 2, when the UE completes the access handover, its call state must change, so the It is feasible to judge the completion of the access handover based on the status. For example, the UE originally provided PS sessions for users. However, due to changes in the location of the UE, the current network test results show that the CS network signal is better than the PS network signal. It is necessary to switch the session from the PS network to the CS network. When the UE detects itself If the call state of the user is switched from the original PS call state to the CS call state, it is considered that the access handover has been completed. In this way, the UE can more simply and reliably judge whether the access handover is completed.

Preferably, in the above-mentioned device, the local ringing module 503 specifically includes: a disconnection unit, used for the UE to disconnect the service connection with the CRS AS; a chromatic image stop unit, used for the UE to stop playing the chromatic image; a local ringing unit, Used by the UE to notify the user of an incoming call with local ringing. In this embodiment, the UE stops receiving chromatic image data by disconnecting the service connection with the CRS AS, and then stops playing the chromatic image. In this way, the UE does not need to process the chromatic image data after determining to perform access handover, which saves UE The resource realizes timely stop of chromatic image.

Preferably, in the above device, the local ringing unit is one of the following: the ringing unit is used for the UE to play a local ringing file for prompting the user to call; the vibration unit is used to remind the user to call by vibration; the ringing A vibration unit is added, which is used for UE to play a local ring tone file while vibrating to prompt the user to call.

In this embodiment, the UE selects one of ringtone, vibration, or ringtone plus vibration according to the policy predetermined by the user to prompt the incoming call. When inbound handover and chromatic image services dependent on the network are affected, local ringtone files or vibrations are played, which improves the reliability of incoming call notifications.

From the above description, it can be seen that the above-mentioned embodiments of the present invention allow the user to still know the correct incoming call information even when the UE undergoes access switching, which improves the reliability of the incoming call prompt and improves the user experience.
